From 8e07227c5853de78eaed4577eefe908fb84507c0 Mon Sep 17 00:00:00 2001 From: Maxime Dénès Date: Tue, 28 Jun 2016 10:55:30 +0200 Subject: A new infrastructure for warnings. On the user side, coqtop and coqc take a list of warning names or categories after -w. No prefix means activate the warning, a "-" prefix means deactivate it, and "+" means turn the warning into an error. Special categories include "all", and "default" which contains the warnings enabled by default. We also provide a vernacular Set Warnings which takes the same flags as argument. Note that coqc now prints warnings. The name and category of a warning are printed with the warning itself. On the developer side, Feedback.msg_warning is still accessible, but the recommended way to print a warning is in two steps: 1) create it by: let warn_my_warning = CWarnings.create ~name:"my-warning" ~category:"my-category" (fun args -> Pp.strbrk ...) 2) print it by: warn_my_warning args --- lib/pp.ml | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'lib/pp.ml') diff --git a/lib/pp.ml b/lib/pp.ml index d07f01b90..f1eb4c059 100644 --- a/lib/pp.ml +++ b/lib/pp.ml @@ -197,6 +197,25 @@ let strbrk s = else if p = n then [] else [str (String.sub s p (n-p))] in List.fold_left (++) Glue.empty (aux 0 0) +let pr_loc_pos loc = + if Loc.is_ghost loc then (str"") + else + let loc = Loc.unloc loc in + int (fst loc) ++ str"-" ++ int (snd loc) + +let pr_loc loc = + if Loc.is_ghost loc then str"" + else + let fname = loc.Loc.fname in + if CString.equal fname "" then + Loc.(str"Toplevel input, characters " ++ int loc.bp ++ + str"-" ++ int loc.ep ++ str":" ++ fnl ()) + else + Loc.(str"File " ++ str "\"" ++ str fname ++ str "\"" ++ + str", line " ++ int loc.line_nb ++ str", characters " ++ + int (loc.bp-loc.bol_pos) ++ str"-" ++ int (loc.ep-loc.bol_pos) ++ + str":" ++ fnl()) + let ismt = is_empty (* boxing commands *) -- cgit v1.2.3
